Showing some skin! On Sunday Demi performed her new track Cool For The Summer on The Voice Australia

Sex appeal: The stunner heated up the stage in black high-waisted hotpants and a matching bralette that put her cleavage on display

After turning heads on stage, Demi spoke to the crowd and she 'loves Australia.'

She added: 'the opportunity [to perform] hasn't come and now it has and I'm so glad.'

Demi flew into Sydney on Saturday, four months after she was last in the country.

In April, she came to Australia for her tour.

Despite appearing body confident on stage, Demi has previously struggled with an eating disorder and has been open about it.

She recently talked to The Kit about the disorder and said, 'every day I am dealing with it.'

'I’ve suffered from eating issues for the past 10 years of my life, give or take, and for me it’s a daily thing when you fall into something that severe for so long–it’s hard not to fall back into it,' Demi said.

She added: 'I’m on a meal plan, I have a trainer, I get fully guided in a way where it’s almost something I don’t have to think about anymore.'
